Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530942, here are decompositions:

31 + 530911 = 530942
73 + 530869 = 530942
109 + 530833 = 530942
199 + 530743 = 530942
211 + 530731 = 530942
229 + 530713 = 530942
241 + 530701 = 530942
283 + 530659 = 530942

Showing the first eight; more decompositions exist.
